Option to play the video slower for subtitleing
An option to play the video slower than the original within the subtitle tool. If you want to offer only one option I'd suggest to go with 0.5 times the original speed.
Sometimes actors are speaking very fast, making it difficult to be certain of what they say. In my experience it can help in such situations to be able to play the segment in a slower maner.
Somewhere on this video controller bar in the subtitle tool.
